India grows about a fifth of the world's tea, more than any country except China, and drinks roughly four-fifths of what it grows itself, a domestic appetite most other major producers cannot match. Almost nothing else about the industry follows from scale alone; it follows from that one ratio. A crop consumed mostly at home answers first to its own dinner table, carries a price cushion the pure exporters do not have, and draws a regulatory hand (the Tea Board, the auction mandate, the GI registry) heavier than a purely export-facing industry would need. What that produces on the ground is documented here: four regions growing four different crops, a small-grower class that now rivals the estate it grew up beside, an auction system a chunk of the industry is actively trying to escape, and an export trade fighting simultaneously on three fronts. The world context around it is set out in Who Grows It; this page is the reference on India specifically.

A colonial plantation crop with an indentured start

Commercial tea growing in India began in Assam. A British-appointed Tea Committee started testing the region's wild tea plant in the early 1830s. The first plantation was laid out at Chabua in 1837, and the Assam Company, formed in 1839 to grow and sell the crop at scale, is the industry's conventional founding point. Demand for labour outstripped what the sparsely populated Brahmaputra valley could supply. British planters answered by recruiting indentured workers from famine-prone districts of Bihar, Odisha, and central India, under contracts that tied them to the garden for years at a time. The recruitment could be lethal: Hindi-language sourcing on the tea garden community's own history records a single 1863 to 1866 drive that brought in nearly 85,000 labourers, of whom close to 30,000 had died, mostly of cholera, by June 1866. That is the beginning of the workforce Assam's tea gardens still draw on today; what that labour is paid now, and how the terms have changed, is set out in What a Tea Garden Worker Earns. The point for this reference is simpler: India's tea industry was built as a plantation export business under colonial administration, and its estate structure, large gardens with a resident workforce and an on-site factory, is a direct inheritance of that start.

Four regions, four different crops

India's tea is not one crop but several, split by geography into regions with genuinely different characters. Assam, the low-lying Brahmaputra valley, is the volume backbone: it alone supplies close to half of India's tea, grown mostly as CTC (the granular, machine-cut black tea that fills most tea bags; the process is set out in How the Trade Works), with a malty, full-bodied liquor from the plains' heat and humidity. West Bengal's Dooars and Terai belt, at the foot of the Himalayas, is the next-largest producer and grows a similar bulk CTC crop. Darjeeling, a small hill district within that same state, is the opposite case: a high-elevation, low-volume, orthodox-manufacture crop prized for a light, muscatel-scented liquor, grown across some 87 gardens, a rounding error in national volume but a name that carries outsized weight (its own section follows). The Nilgiri hills in the south, at elevations of roughly 1,000 to 2,500 metres (about 3,300 to 8,200 feet), grow a fourth character entirely: a bright, brisk, floral orthodox tea that goes disproportionately into iced tea and blended exports rather than the loose-leaf market Darjeeling and Assam orthodox compete in.

The small grower who now grows more of it than the estate

The industry's biggest structural shift is not in the plains or the hills. It is in who owns the bush. India's tea was built on the estate model: a resident company running its own gardens and its own factory. That is still how the classic Assam and Darjeeling names are grown. But over the past three decades, a parallel sector has grown to rival and in places overtake the estates: independent small tea growers, farmers cultivating tea on a few acres or less who sell their green leaf to a separate "bought-leaf" factory. Estimates vary by source and season, but small growers now account for roughly half of Assam's own output, farming plots that were, within living memory, growing rice rather than tea. IDH, the sustainable-trade initiative that works with the sector, counts more than 120,000 registered small growers in Assam alone, and the true figure is likely higher once growers too small to register formally are counted. Most small growers do not sell straight to a factory. Surveys have found the large majority selling instead through intermediary agents, who take a cut before the leaf ever reaches a weighing scale, a squeeze the estate sector does not face since it owns its own factories. Who Grows It sets out the wider economics of that split, who bears the price risk and who captures the margin. India's version is stark: the newer, smaller side of the industry now supplies most of the leaf in its largest producing state, without owning any of the machinery that turns it into made tea.

Sold at auction, sometimes by law

India sells its tea through a network of public auction centres, the mechanism common to major producing countries and set out in general in The Auctions. India runs seven of them: Kolkata and Guwahati in the north, Siliguri for the Dooars, Darjeeling, and Terai gardens, Cochin, Coonoor, and Coimbatore in the south, and a smaller centre at Amritsar. Guwahati opened in 1970 to serve the Assam plains and grew into the busiest CTC auction floor in the world by volume. Kolkata's auction, the older of the two, moved its CTC, dust, and Assam orthodox sales onto an electronic platform between 2009 and 2011, leaving only Darjeeling lots sold the traditional way. What is distinctly Indian is not the mechanism but a rule sitting on top of it. Since 2015, registered manufacturers have been required to sell at least half their annual production through public auction rather than direct, private sale. The rule went largely unenforced for years. Then a fresh circular reviving it drew a joint appeal from four grower associations, representing close to 60 percent of north India's output, asking the government to withdraw it: auction sales, they argue, carry roughly ₹10 a kilogram (about 12 US cents) in extra transaction cost and a longer selling cycle than a direct deal. That specific fight, and how the government has responded, is tracked in Assam and Bengal Tea Bodies Ask Modi to Drop the 50% Auction Rule. The reference point here is simpler: India, alone among the major producers, has spent a decade trying to mandate the auction channel by regulation rather than leaving producers to choose it on the merits.

Grown mostly, and drunk mostly, at home

The fact that sets India apart from every other major producer is on the demand side, not the supply side. Roughly 80 percent of the tea India grows is consumed inside the country, a domestic market that has grown by around a quarter over the past decade alone, leaving only about a fifth for export. That is close to the inverse of Kenya or Sri Lanka, which export nearly everything they grow (see Who Grows It), and it means India's tea economy answers first to its own consumers rather than the international auctions that set the world price. The export fifth is still substantial in absolute terms and had a record year in the most recent full reporting period, with Iraq, the United Arab Emirates, Russia, and the United States its established leading buyers, West Asia and the former Soviet market together taking close to half the total. Exporters are pushing further into China, North Africa, and Egypt on top of that base, diversification the industry has leaned on harder since shipping disruption made the West Asian route less dependable (tracked in India's Tea Exports Hit Record ₹8,718.83 Crore in FY 2025-26). But the domestic cup is the industry's real floor: whatever happens to the export order book, four out of every five kilograms India grows are going to be drunk by Indians.

Darjeeling's shrinking, legally defended name

Darjeeling occupies a place in India's tea industry out of all proportion to its output. It was the first product of any kind registered as a geographical indication in India, granted that status in 2004 under the country's GI Act. The name is a protected legal asset: tea grown outside the district's roughly 87 gardens cannot legally be sold as Darjeeling, the same logic that protects Champagne or Parmesan. That legal wall has not protected the volume behind it. Darjeeling's annual output has fallen from around 12 million kilograms a decade ago to roughly 6 million kilograms in the most recent full season, driven by aging tea bushes, erratic rainfall linked to a warming climate, and cheaper leaf crossing in from Nepal's neighbouring Ilam and Jhapa districts, which grows tea from the same botanical stock at the same elevations and is frequently blended into or passed off as the more valuable Darjeeling name. The industry's own complaint is less about competition than mislabelling: authentic Darjeeling produced at real cost is undercut by tea that legally cannot carry the name but is sold, informally, as if it could, a live dispute followed in Indian Testing Rules Halt Nepali Tea Trade as Darjeeling Brand Dispute Resurfaces. Darjeeling is the clearest illustration in India's tea industry of a name that a legal protection alone could not keep from shrinking.

A trade fighting on three fronts

Beyond the auction dispute, India's export side answers to pressure from two other directions at once, each a case study in how a single policy or shock ripples through a major producer's trade. A free-trade agreement with the European Union zeroed out the tariff on tea exports, a genuine gain, arriving almost together with a tighter EU pesticide-residue limit that threatens a meaningful share of Assam's exports to that same market: a tariff win and a technical-standard loss on the same route (tracked in India-EU Trade Deal Zeroes Out Tea Tariffs as a Stricter EU Pesticide Limit Looms). Separately, a shipping crisis across West Asia, the destination for close to half of India's tea exports and nearly all of its orthodox grade, cut a recent quarter's exports sharply, forcing orthodox shippers in particular onto longer, costlier routes (tracked in West Asia Shipping Crisis Cuts India's Q1 Tea Exports 17%). None of these three pressures, the auction mandate, the EU standard, the shipping squeeze, is large enough alone to move India's overall trade balance much. Together they explain how an industry reporting record export earnings can, in the same season, have its producer associations writing to the prime minister asking for relief.

Why the domestic cup is the real story

Every dispute in this reference, the auction mandate, the EU pesticide standard, the West Asian shipping squeeze, plays out on the export fifth of India's crop. That is not an accident of what makes news; it is a consequence of the ratio at the top of this page. An industry that sold most of what it grew abroad would answer first to the world price and would have organised itself around exporters, brokers, and the auction floor. India organised itself around its own market instead, which is why a small-grower class barely a generation old could rise to rival a century-old estate sector without the world market forcing the issue either way, and why a name as small as Darjeeling's 87 gardens can carry a legal shield most producing countries never bother building. Read any figure in India's tea trade against that ratio, four-fifths drunk at home, one-fifth exported and contested, and the rest of the industry's shape stops looking like a set of separate stories and starts looking like one structure.
